When the Korean War started, 90,000 troops from North Korea forced South Korea’s troops to retreat. By the time September rolled around, the United Nations troops were not faring any better, and the Americans were set on a tiny part o the Peninsula, not making much progress.
American and South Korean forces worked together to hold a line eventually known as the Pusan Perimeter. Finally, on September 15, 1950, the United States Marines led by United Nations Supreme Commander Douglas MacArthur landed at Inchon. The Army, Marines, Navy, and Air Force all planned to land behind enemy lines in a team effort.
As soon as the Army came through the Pusan Perimeter, the North Korean’s dispersed. At the same time, the Marines were landing at Inchon. It took UN forces two weeks to take back part of Seoul.
From there, they severed the North Korean’s supplies and communications. Operation Chromite was deemed to be very hazardous, but the United States Marine’s amphibious assault was successful. It was also the largest water invasion since World War II.
Four Day Assault
The surprise assault included 261 naval vessels and lasted for four days. The battle marked the ending of North Korea’s winning streak with their long string of victorious battles.
The KPA was outnumbered six to one by the United Nations troops, taking on 200 casualties and capturing 136.
Because of the invasion’s success, the capital of South Korea, Seoul, was taken back from North Korea. In the month that followed the landing, the U.S troops took 135,000 KPA troops, prisoner.
However, much of the forward progress that the South Korean and United States forces were making was halted by the Chinese military when they joined the war.
Due to their involvement, there was no clear victor in the war that drug on for three long years.
